designed to foster compliance with insider trading laws, rules, and regulations, and the listing standards of the 
Nasdaq  Global  Select  Market  that  will  be  applicable  to  us.  Our  Insider  Trading  Policy  applies  to  all  of  our 
officers,  directors,  and  employees,  as  well  as  designated  consultants,  and  specifically  prohibits  ownership  of 
financial  instruments  or  participation  in  investment  strategies  that  hedge  the  economic  risk  of  owning  our 
equity  securities,  such  as  prepaid  variable  forwards,  equity  swaps,  and  collars.  Directors,  officers,  and  other 
employees  are  prohibited  from  maintaining  company  securities  in  a  margin  account  or  otherwise  pledging 
company  securities  as  collateral  for  a  loan,  provided  that  certain  limited  exceptions  may  be  permitted.  In 
addition, we prohibit our executive officers, directors, and employees from purchasing or selling our securities 
while  in  possession  of  material,  non-public  information  or  otherwise  utilizing  such  information  for  their 
personal benefit. We maintain a quarterly blackout window where applicable individuals may not trade. 

Policies and Practices Related to the Grant of Certain Equity Awards Close in Time to the 
Release of Material Nonpublic Information

We periodically grant stock options to our NEOs, employees, and other service providers. We have historically 
granted  options  on  or  shortly  after  a  newly  hired  employee’s  start  date.  We  have  historically  granted  refresh, 
promotion,  or  market  adjustment  options  when  and  as  determined  by  our  board  of  directors.  We  have  no 
specific  policy  or  practice  regarding  the  timing  of  options  or  other  equity  grants  in  relation  to  the  public 
disclosure of material nonpublic information by the company.

Tax and Accounting Considerations

Tax Considerations

Section 162(m) of the Code imposes a $1 million limit on the amount of compensation that we may deduct as a 
business expense in any year with regard to certain of our most highly paid executive officers. While our board 
of directors considers the deductibility of compensation as one factor in determining executive compensation, 
our board of directors retains the discretion to award compensation that is not deductible as it believes that it is 
in  our  best  interests  to  maintain  flexibility  in  our  approach  to  executive  compensation  in  order  to  design  a 
program  that  we  deem  to  be  the  most  effective  in  attracting,  motivating,  and  retaining  key  executives  and 
aligning pay with performance.

Accounting Considerations

Our  board  of  directors  takes  accounting  considerations  into  account  in  designing  compensation  plans  and 
arrangements  for  our  NEOs  and  other  employees.  We  follow  the  Financial  Accounting  Standards  Board’s 
Accounting  Standards  Codification  Topic  718  (“FASB  ASC  Topic  718”)  for  our  stock-based  compensation 
awards.  FASB  ASC  Topic  718  requires  us  to  measure  the  compensation  expense  for  all  share-based  payment 
awards based on the grant date “fair value” of these awards.

The  following  table shows  the  compensation  awarded,  paid  to,  or  earned  by  each  of  our  NEOs for  the  year

The review

Three primary reviewers read non-overlapping ranges of the complete main filing. All 43 embedded image instances were transcribed and visually reviewed, including the founders’ letter, charts, and customer case studies. Financial tables were also checked visually for dates, units, and column alignment.

A separate reviewer checked the draft’s calculations, accounting interpretations, and customer qualifications. An additional check covered the later merged findings. The result is 62 findings and 21 customer examples.

The boundary

Companion contracts and other exhibits named in the filing’s index are separate documents and were not independently reviewed. Customer outcomes, technical benchmarks, forecasts, and scientific priority claims remain attributed company or customer disclosures.

The numbers

Dollar figures are U.S. dollars. H1 means the six months ended June 30; Q2 means the three months ended June 30. The 2026 interim financial statements are unaudited. Our calculations show their inputs and are labeled separately from reported values.

Blank fields stay undisclosed. Figures with different periods, conditions, or potentially overlapping scopes are kept separate. An earlier tender price is not an IPO price.

What the evidence labels mean
Reported in filing
A company disclosure, with the period and accounting basis retained.
Company estimate / company claim
An estimate or assertion attributed to the company, with its uncertainty preserved.
Our calculation
A derived figure using cited inputs. It is not a separately reported company metric.
Customer example
A selected case study, with its measurement limits. It is not representative ROI.
Proposed / conditional
A status qualifier for an arrangement that is not yet effective or depends on stated conditions.

About updates. This edition is tied to the October 26, 2026 filing. Any later revision should identify its new source date and preserve the basis of earlier claims.
